IMPROVEMENT IN HARROWS.

Specification forming part of Letters Patent No. 181,849, datedSeptember 5, 1876; application filed July 15, 1876.

To all whom it may concern:

Be it known that I, SAMUEL KAIN, of Bethany, in the county of Butler andState of Ohio, have invented certain new and useful Improvements inHarrows; and I do hereby declare the following to be a full, clear, andexact description of the same.

This invention relates to that class of barrows formed'of detachablesections hinged together to allow it to accommodate itself toinequalities in the ground; and my improvements consist in the manner ofhinging the sections, and in the construction of the toothbeams, and themanner of securing the teeth thereto, all as will be herewith describedand specified. I

To enable others skilled in the art to which my invention appertains tomake and use the same, I would thus proceed to describe it, referring tothe accompanying drawing, in which- Figure 1 represents a plan view ofmy improved harrow. Fig. 2 is a side elevation of the same. Fig. 3 is anend elevation, showing the drop for fastening the hinges.

Corresponding letters of reference indicate like parts in all thefigures.

AA represent wooden beams of the size usual in barrows of thisdescription, but each having one of its edges beveled, as represented..These beams are parallel to each other, and in the central section(which is composed of three) are braced by two end metal bars, B, atright angles to the beams to which they are bolted, and by a centraldiagonal bar, 0, likewise bolted to the beams. The two usual runners Dare bolted upon the bars B, as represented. The ends of the bars B areformed into gudgeons I), over which the loop 0, upon the ends of thebars E that brace the outer sections or wings, are slipped, thus forminghinges upon which the wings can play to accommodate them to theinequalities of the ground. The wings are braced in the same manner asthe central section.

It will be noticed that they are placed at some distance from thecentral section, so that their own weight will be sufficient to keepthem down to work.

It will also be noticed that the gudgeons on which the hinges turn liein opposite directionsthat is, in the section A, to which the draft isapplied. The loops on the bars E are on the right of the bars B, lookingback in the line of draft a; 00, while the loops on the brace-bars ofthe rear wing are on the opposite side of the bars B.

By this arrangement it can be clearly seen that it is impossible for thesections to become accidentally detached while at work but to rendertheir junction more secureI provide the latches or detents G, Fig. 3,which, bolted to the sides of the beams A, can be pressed down to restupon the projecting end of the gudgeon, and abut against the edges ofthe loops, thus preventing their removal until the detents be raised.Two of these detents, as

represented in the drawing, are sufficient On the beveled side of eachbeam A are equidistant gains or mortises, in which the teeth H fit, andwhich are given the proper inclination. The teeth, which are of theordinary shape, do not entirely fill up these gains, and over the partwhich projects is fitted a metal clampingplate, a, which is held byscrew-bolts, which enter the beam on each side of the teeth, asrepresented. These plates securely hold the teeth in position, and byslightly loosening the bolts they maybe moved up or down to suit thecharacter of the work to be done. The vertical sides of the beams arelikewise mortised and provided with clamping-plates, so that the teethmay be changed at pleasure from an inclined to a vertical position.

I am aware that teeth have been made adjustable in a harrow by means ofan adjustable eyebolt fastening without removing them but such method ofadjusting them is not so secure as the one I describe.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is as follows:

1. In a harrow the beams A, each having one side beveled and theopposite side vertidal, and both mortised substantially as depivotedlatches or detents G, substantially in scribed, for holding the teetheither in a verthe manner and for the purpose specified. tical oruslanting direction,in the manner and Witness my hand this 29th day ofJune,

for the purpose specified. A. D. 1876.

2. In a sectional hinged barrow the hinges, SAMUEL KAIN. composed of thegudgeons b and loops 0, Witnesses: when arranged inopposite directionsto each CHAS. M. PEGK, other, and held from displacement by the MICHAELRUBLE.
